What exactly is voltage_min_design kernel attr?
I’d experienced random shutdowns when the battery capacity was under ~70% and during power-intensive operations (CPU, display backlight). The default voltage_min_design value was 3.3V. I lowered it to 2.9V, and everything works fine now. Unfortunately, I also started charging calibration, so I can’t be sure what fixed the issue.
My 18650 battery Cutoff Voltage is 2.5V. Min voltage of 3.3V seems too high for me. Does some default power management tool in Debian use voltage_min_design to cut the power when voltage drops below voltage_min_design? It certainly looked like this. But is it correct?
